Some valves require dithering to prevent stiction. At this time, the RMC75 and RMC150 do not have a built-in dithering feature, but dithering can be done with a user program.
The attached project has two different programs that implement dither by continuously changing the Output Bias. One program only applies dither when the axis is stopped (in position control), and the other applies dither continuously.
A dither user program should always run. You can create a “_FirstScan” condition in the Program Triggers to start this user program when the RMC eneters Run mode.
